The 22 nanometer (22 nm) lithography process is a full node semiconductor manufacturing process following the 28 nm process stopgap. The term "22 nm" is simply a commercial name for a generation of a certain size and its technology, as opposed to gate length or half pitch. Commercial integrated circuit manufacturing using 22 nm process began in 2008 for memory and 2012 for MPUs. This technology was replaced by with 20 nm process (HN) in 2014 and 16 nm process (FN) in late 2015.

The 22 nm became Intel's first generation of Tri-gate FinFET transistors and the first such transistor on the market. This process became 3rd generation high-k + metal gate transistors for Intel. In 2017 Intel announce the introduction of a new process "22FFL" specifically for low power IOT and mobile products for their custom foundry.
